Objective To analyze the second time blood screening results of ALT deferred donors,and to evaluate the importance of alanine aminotransferase(ALT) testing on the improvement of blood safety.Methods The ALT testing results of 565 360 blood donors from Feb.2006 to Jan.2008 of Shanghai Blood Center were studied retrospectively.The screening results and donation intervals of such donors who delayed their donation just because of their former unqualified ALT level were also analyzed.Results A total of 32 042 donors(5.67%) failed in ALT testing among 565 360 donors.And 3 395 ALT deferred donors participated the second time blood donation,among which 2 205(64.95%) passed the blood screening tests,while the other 1 190(35.05%) failed.Among the 1 190 unqualified blood donors,1 151(33.90%)failed again in ALT testing,and 11(0.32%) in Syphilis,12(0.35%) in HBsAg,7(0.21%) in anti-HCV and 1 in anit-HIV(0.03%).Meanwhile,donors failed both in ALT testing combined with HBsAg,anti-HCV,and anit-HIV sero-converted were 1(0.03%),2(0.06%) and 1(0.03%),respectively.And 72.64% of ALT deferred donors participated the second time blood donation within 6 months.The average donation intervals of donors with qualified ALT level but sero-converted were 140 days(from 24 to 267 days),and those with both unqualified ALT level and sero-converted were 158 days(from 91 to 220 days).Conclusion Before the new methods such as NAT were applied to blood donation screening system,ALT test could prevent the window-period failure of ELISA screening so as to improve the blood safety.

To summarize the experience about the preoperative and postoperative nursing of 11 cases with neurogenic bladder treated by sacral neuromodulation. The main nursing interventions of this procedure involved accurate recording of voiding diaries and postvoid residual, effective psychological nursing and health education of related disease information, standard videourodynamic examination. 11 patients acquired more or less benefit after the screening test and were discharged successfully, among them 2 cases had the permanent implantation of the stimulation device.

ObjectiveTo investigate advantage and disadvantage of different rehabilitation therapies used for cerebral palsy (CP) children complicated with epilepsy (EP).Methods140 CP children complicated with EP screened from 1402 CP cases, were analyzed for CP and EP types, MRI or CT, brain stem auditory evoked potentials (BAEP). All cases were treated with anti-epilepsy drugs (AEDs). Different rehabilitation therapies, including electrotherapeutic modalities, acupuncture, point injection, cerebroprotein hydrolysate injection, manual therapy, functional training, Chinese herb braising therapy, and cattle encephalon glycoside and ignotin injection were assessed.ResultsIn all 140 cases, a majority of EP types were myoclonic seizure and west syndrome, CP type was spasticity. Abnormality showed in MRI or CT (98%) and BAEP (90%). AEDs were effective for all 140 cases. Electrotherapeutic modalities, acupuncture, point injection, and cerebroprotein hydrolysate injection could make EP severely, but manual therapy, functional training, Chinese herb braising therapy, cattle encephalon glycoside and ignotin injection had no adverse effects on EP cases.ConclusionThe principles of rehabilitation treatment for the CP children complicated with EP are taking AEDs early and in a long term, avoiding electrotherapeutic modalities, acupuncture, point injection, and cerebroprotein hydrolysate injection, using manual therapy, functional training, Chinese herb braising therapy, and cattle encephalon glycoside and ignotin injection.

AIM: To summarize clinical characteristics and pathogenesis of iridocorneal endothelial syndrome ( ICE ) and investigate the treatment and prognosis.
METHODS:The clinical data of 12 cases (12 eyes) who received treatment in southwest hospital during Jun. 2007 to Feb. 2015 were analyzed retrospectively. The essential progressive atrophy of iris included 7 eyes, Chandler syndrome included 3 eyes, Congan - Reese syndrome included 2 eyes.
RESULTS: A total of 8 eyes were carried out once or multiple filtration surgery; 4 eyes were treated with glaucoma valve implantation. Postoperative follow- up time ranged from 15mo to 5y with the average of 30mo. Three months to 16mo after the surgery, the intraocular pressure of 4 patients were elevated again. Postoperative intraocular pressure was poorly controlled.
CONCLUSION:ICE syndrome is a group of clinically rare and serious eye disease. The excessive proliferation of ICE cells causes the existence of the corneal endothelial cells adhesion to the chamber angle and iris surface, which cause iris atrophy, secondary glaucoma, corneal endothelial decompensation. Currently, glaucoma filtration surgery and glaucoma valve implantation can only control intraocular pressure for several months, but the long-term prognosis is poor.

Objective: To explore the pattem of lymphatic metastasis and influencing factors of thoracic esophageal carcinoma. Methods: We reviewed the pathological specimens from 229 esophageal carcinoma patients who underwent radical esophagectomy with two-field lymphadenectomy. A total of 2,458 lymph nodes were dissected. We analyzed the lymph node metastasis pattern of the primary tumor in different loca-tions and the corresponding influencing factors such as pathological T stage, tumor length, pathological mor-phology and tumor differentiation. Results: Lymph node metastasis rates were 44.5% (102/229) and 10.5% (258/2458), respectively. For patients with upper thoracic esophageal carcinomas, lymphatic metastasis rates in the superior mediastinum, the middle mediastinum, the inferior mediastinum and the abdominal cavity were 19.0%, 6.7%, 9.8% and 12.2%, respectively. For patients with middle thoracic esophageal carcinomas, the rates were 26.1%, 7.4%, 11.8% and 11.9%, respectively. For patietns with lower thoracic esophageal carcino-mas, the rates were 0, 1.6%, 5.3%, and 10.0%, respectively. Lymphatic metastasis rate in T_1, T_2, T_3, T_4, stage cancer were 28.6%, 43.8%, 47.6%, and 31.3%, respectively; the rate of positive lymph nodes were 7.9%, 10.8%, 10.7%, and 10.8%, respectively, with no significant differences among the four stages (x~2=2.733, P=0.435 and x~2=0.686, P=0.876). Lymphatic metastasis rate and rate of positive lymph nodes in patients with tu-mor ≤3cm, 3 to 5cm, and >5cm were 45.2% and 43.4%, 46.2% and 9.1%, and 11.6% and 11.7%, respective-ly, with no significant differences (x~2=0.094, P=0.954 and x~2=3.933, P=0.140). Lymphatic metastasis ratios of the pathological morphology in medullary, ulcerative, mushroom and stenotic types were 14.0%, 9.6%, 4.3% and 18.3%, respectively (x~2=19.292, P=0.000). Lymphatic metastasis rate and rate of positive lymph nodes of squamous cell carcinoma of moderately and poorly differentiation were 42.5%, 75.0% and 9.5%, 18.6%, re-spectively (x~2=4.852, P=0.028 and x~2=11.323, P=0.001). Patients with squamous cell carcinoma of poorly dif-ferentiation had a higher rate of lymph node metastasis. Conclusion: Lymphatic metastasis of esophageal car-cinoma metastasize widely even if in early T stage. Pathological morphology and tumor differentiation are re-lating facors of lymph node metastasis of thoracic esophageal carcinoma.

Objective To investigate the result and side effect of late course accelerated three-di-mensional conformal radiotherapy (3DCRT) for esophageal carcinoma. Methods From July 2003 to March 2006, 55 patients with esophageal carcinoma receiving 3DCRT were randomly divided into late course accel-erated radiation group (group A, 27 patients) and conventional fractionation group (group B, 28 patients). The prescribed dose in group B was 64 -66 Gy, 2 Gy per fraction, 1 fraction per day, 5 fractions per week for about 6.5 weeks. Patients in group A received conventional fractionation irradiation for the first 4 weeks. Then the dose was increased to 3 Gy per fraction to a total dose of 67 -70 Gy. The treatment course in group A was about 6 weeks. The treatment response, acute site effects, 1-, 3-and 5-year local control rates and o-verall survival rates of the two groups were observed. Results In group A, 23 patients (85%) achievedcomplete response (CR) and 4(15%) achieved partial response (PR). While in group B, 16 patients (57%) achieved CR and 12(43%) achieved PR. The CR rate was significant higher in group A (χ~2 = 5.24,P=0.022). The 1-, 3-, 5-year local control rates were 85%, 54%, 54% in group A, and 70%, 56%, 33 % in group B (χ~2 = 0.68, P = 0.409), respectively. The 1 -,3-,5-year overall survival rates of the two groups were 81%, 37%, 29% and 61%, 39%, 23% (χ~2 = 0.06, P = O. 804), respectively. Both lo-cal control and overall survival were similar between the two groups. The incidences of acute radiation esoph-agitis in the two groups were similar (85% vs. 89% ;χ~2 =0. 00,P=0. 959), and the incidence of radiation pneumonitis was slightly higher in group A than in group B (67% vs 43% ;χ~2 =3.14,P =0.076). By the last follow up, 19 patients in group A and 21 in group B died. Among them, 10 in group A and 15 in group B died of local failure, while 7 in group A and 5 in group B died of metastasis. Conclusions When com-pared with conventional fractionation 3DCRT, late course accelerated 3DCRT for esophageal carcinoma can achieve better results in clinical response, though not in long-term local control or survival. The incidence of acute radiation esophagitis and pneumonitis is clinically acceptable.

Objective To investigate the association between single nucleotide polymorphism (SNP) of macrophage migration inhibitory factor (MIF) gene-rs1007888 and the pathogenesis of gestational diabetes mellitus (GDM).Methods A total of 120 GDM pregnant women (GDM group) and 165 healthy pregnant women (control group) from Affiliated Hospital of Medical College,Qingdao University were recruited from June 2011 to July 2012.Their age,gestational week,height and weight were recorded.The levels of fasting blood glucose (FBG) and fasting insulin (FIN) were determined.Body mass index (BMI),the hemeostasis model assessment-insulin resistance (HOMA-IR) and hemeostasis model assessment-β cell function (HOMA-β) were calculated.DNA was extracted from fasting blood samples.SNP of MIFrs1007888G/A was determined by DNA sequencing.The FBG,FIN,HOMA-IR and HOMA-β were compared between GDM group and the control group.They were also compared among pregnancies withdifferent genotypes.Results (1) GDM group had higher FBG,FIN and HOMA-IR levels,but lower HOMA-β than the control group (all P ＜ 0.05).(2) MIF-rs1007888 SNP genotype frequencies of GG,GA and AA were 37.5％,45.8％ and 16.7％,and the allelic frequencies of G and A were 60.4％,39.6％ in GDM group; However,in the control group,the frequencies of GG,GA and AA were 26.1％,54.5％ and 19.4％,and the allelic frequencies of G and A were 53.3％,46.7％,respectively.The distributions of MIF genotypes in GDM patients were significantly different from the healthy subjects (P ＜ 0.05).No significant difference of MIF-rs1007888 allele distributions was observed between GDM group and the control group (P ＞0.05).(3) The FBG,FIN and HOMA-IR in pregnant women with GG genotype were statistically higher than those with GA or AA genotypes,while HOMA-β was lower in women with GG genotype (all P ＜0.05).Conclusions The SNP of MIF rs-1007888 was related to the insulin resistance and pancreatic β cell function of pregnant women.GG genotype of MIF-rsl007888 might be a genetic susceptible factor in the pathogenesis of GDM.
